ROTARY MOLDING-MACHINE FOR SHAPING METAL SHEETS.

SPECIFICATION forming part of Letters Patent N 0. 636,341, dated November '7, 1899.. Application filed June 9, 1899. Serial No. 719,917. (No model.)

To all whom it may concern:

Be it known that I, EDWARD JORDAN, plumber and metal-Worker, a subject of the Queen of Great Britain and Ireland,and a resident of Sydney, in the Colony of New South Wales, have invented a certain new and useful Rotary Molding-Machine for Shaping Metal Sheets, of which the following is a specification.

The object of this invention is to convert flat sheets of metal into various forms to render them adaptable to avarietyof useful purposes, such as moldings, cornlces, ogee and half-round guttering, and the like. It is likewise serviceable to perform certain operations known as beading and wiring.

In the one machine it is sought to combine several useful operations, so as to produce the results above stated, and,-further, by the adaptation of interchangeable parts to the molding devices varying results are to be obbe operated by any suitable power, and its action can be made either intermittent or continuous.

The invention is illustrated by the accompanying drawings, in which similar letters are used in connection with the various figures to indicate similar parts, and in which-- Figure 1 is a side elevation of a rotary molding-machine adapted to produce by partial and reverse revolutions two forms of molded articlesand serviceable for performing beading operations. Fig. 2 is an elevation of one end of Fig. 1, showing gearing used for driving the machine. Fig. 3 is an elevation of the other end of Fig. 1, showing equal gear-wheels and balance -weight attached to the rotary molding-dies. Fig. 4 is an elevation of part of astandard with gearing removed to show movable bearing and compensating spring for same. Fig. 5 is a detail of a detachable molding-strip adapted to form a slit or recess to receive the metal sheets and to form the bead of ogee guttering. Fig. 6 is a detail of a detachable and interchangeable strip serviceable to produce ogee guttering of various dimensions. Fig. 7 is a sectional detail of a pair of rotary molding-dies suitable for shaping ogee guttering and beading and illustrating the progress of the molding operation. Fig. 8 is a section similar to Fig. 7, showing partial revolution of the moldingdies and one size of ogee guttering completed, also a sheet of metal in position to be molded during the return movement of the dies, so as to produce another size of guttering. Fig. 9 is a section of ogee guttering as shaped by the rotary molding-dies shown in Figs. 7 and 8. Fig. 10 is a section of metal sheet with beading as produced by a beading device attached to the molding-dies. Fig. 11 is a sectional detail of rotary molding-dies similar to Figs. 7 and .8, but with beading parts omitted and surface fitted to receive a variety of forms of rotary molding-dies. Fig. 12 is a section of a molding produced by the removable dies, as shown on Figs. 11 and 13. Fig. 13 is a sectional detail of rotary molding-dies which may be adapted toa machine designed to produce complete and continuous revolutions.

The general construction and manner of operating the machine and shaping the metal sheets are as follows:

The end frames A, secured by the tie-bolts B, are provided with the U-shaped caps'Oto receive the bottom bearings D and upper movable bearings E, in which the journals F and G respectively revolve, such journals forming part of the bottom rotary molding-dies H and'the top molding-dies I. The spur-wheels J, keyed to the journal ends, are equally geared, so as to actuate the rotary dies H and I at the same speed.

The bottom bearings D are seated as shown in Fig. 4,; while the upper bearingsE are held by the springs K, which are kept in position by the standard-caps L, secured by the bolts M, to be adjusted as required. The springs are needful to keep the convoluted surfaces of the rotary dies in contact with each other when in motion and to prevent jarring, at the same time accommodating the dies to the thickness of the metal sheets and insuring the requisite gripping or biting action which is essential to the production of the molded article.

To the rotary die I (which is peculiarly shaped for the special purposes indicated) the lever N is attached, carrying the adjustable balance-wcight O, secured by the bolt P. This weight insures the easy working of the die I and produces regularity of action.

The outer standard Q, together with one of the standards A, is provided with hearings to support the shaft It, carrying the pinion S and handle T for manual power, and also the counter-shaft U, carrying the spur-wheel V and pinion \V. (Shown dotted in Fig. 2.) These, together with the before-mentioned equally-geared wheels J constitute the gearing for operating the machine; but the method of operating may be varied according to circumstances and the power available for driving. Such power may be either steam, hydraulic, or other suitable power. One form of gearing which may be considered particularly applicable to produce the semirotary movement would consist ofa double-toothed rack-and-pinion movement operating reciprocally in the same manner as a steam or hydraulic piston.

When using the machine to make ogee guttering, the rotary dies H and I are made as shown in Figs. 7, 8, and 11. Upon the bottom die H the bead-molding strip (which is made detachable) is secured in position with screws, and to provide for the insertion of the metal sheet ithe slit or recess Y is constructed. Such a recess is also used for other forms of moldings. The convoluted surfaces of the dies are made to correspond in dimension to the size of the article to be shaped. Hence the enlarging and reducing strips Z are made interchangeable and may be transformed from the positions shown on die H to the horns a on the die I.

In Fig. 7 the metal sheet i is shown folded around the head A and assuming the desired shape. As the convoluted surfaces of the dies are brought into contact with each other the movement continues in the direction indicated by the arrows until the horn a is brought into contact with its corresponding part,when the molding operation is completed and the machine is stopped.

In Fig. 8 the dies are shown moving in the reverse direction to Fig. 7, the completed molded article being ready for removal, and another sheet is shown in position on the opposite side ready for molding. It is to be ob- 6o served that the peculiar feature of the invention consists in first securing the sheet of metal and then winding it gradually around and pressing it into the peculiar shape of the block mold.

The rounded surface 11 of the die H is provided with the rounded channels a, which when used in combination with the surface d of the die I serve to produce a beaded sheet by pressing a rod of any suitable diameter into the metal and curling it, as shown in Fig. 10.

In Fig. 11 the beading parts are omitted and another form of molding substituted, and in producing which the operation already described for producing ogee guttering is repeated, and similar results are obtained.

In Fig. 13 the shape of the rotary die is altered so as to produce a number of blank surfaces e, on which a number of molding devicesf and g may be secured, and because of the omission of the horns a the motion of the dies II and I may be made continuous instead of intermittent.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In rotary molding-machines for shaping metal sheets, the combination of a verticallymovable uppercylindrical die with a spring forcing the said die down, a lever and balance-weight attached to said die, a lower, relatively stationary, cylindrical die, interchangeable shaping-strips attached to said dies and adapted to enlarge or reduce their operative periphery, means for attaching to one of the said dies an edge of the metal sheet that is to be operated on and means for supporting and rotating the said dies, substantially as set forth.

2. In rotary molding-machines, an upper rotary die provided with two lateral horns of convex surface in combination with a lower rotary die having corresponding concave surfaces, a shaping-die strip adapted to be transferred from the concave surface of one die to the convex surface of the other and vice versa, means for fastening one edge of a metal strip to one of the said dies and means for supporting and rotating the said dies in order that the said sheet may be shaped between them, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EDWARD JORDAN.
